Problem with bilda and Windows, Linux

[nain-nain rom]

Hello

First, I'm sorry to speak in english but I don't practise German.

I built the Bilda DAC and I want to install it with Windows. I succeded but I have to plug and unplug the DAC many times before Windows recognize it. I removed the EEPROM because with the EEPROM, the DAC is never recognized.

I also tried to install it on linux (Kubuntu, kernel 2.6) and that's the result :

Code: Select all

I think that the problem comes from this part :

Code: Select all

        echo "  ERROR: Kernel configuration is invalid.";               \
        echo "         include/linux/autoconf.h or include/config/auto.conf are missing.";      \
        echo "         Run 'make oldconfig && make prepare' on kernel src to fix it.";

Could you help me ?

Hello

I had the same problem with the EEPROM.

This is a bug in the software.

I didit this way: I put a switch in the positive wire of the EEPROM.

Before I turn on the main power of the bILDA, I switch off the EEPROM. When Windows recogniced bILDA, I turn the EEPROM on and start Popelscan.

If you want to use HE-Laserscan, you don't need the EEPROM


I hope, I was able to help you.

[nain-nain rom]

I use He Laserscan and I saw that it works without the EEPROM. But the problem with pluging and unpluging the DAC is very boring. Few weeks ago, I went to a laserfreak meeting. At the beginning, I had to plug and unplug the DAC only one times. But later, I moved my PC and the projector, the DAC didn't work no more I tried all the night and I didn't succeded.
The next week, I tried at home and it worked unpluging it only one time. The problem is irregular.

[fesix]

Maybe there is a problem with some contacts or something like that?

[nain-nain rom]

Hello

I tried to install it with linux and I learned that bilda isn't compatible with kernel 2.6.
About windows, in the french forum, we said me that the problem could be a wrong value of C20 on the RESET pin. Else, I should add a kondensator in parallel with the R44 on the Vbus.

en fait ce circuit n'a pas les memes broches, mais tu peux essayer avec un condo de 470nF en parallele avec R44 sur le VBUS, car la patte du 18F4550 sur laquelle etait ce condo porte le meme nom... ca doit etre une patte du microcontroleur qui fais office de verification de la tension

un condensateur plus eleve a la place de C20 sur la patte RESET peux aussi resoudre le probleme car il se peut que ton microcontroleur s'active trop rapidement (un "timeout" dans le code qui pense que le micro prend trop de temps avant de recevoir les premieres trames USB), ou alors un condensateur plus petit, si jamais le micro est encore en veille lorsque les premieres trames arrivent

What is the minimal current to supply to this DAC. It could be a power supply too low ?

[fesix]

The minimal Current is abaout 310mA (my bILDA).

[nain-nain rom]

ok thank you
I'll explain more the problem. Some times, I plug the DAC and windows recognize it without problem. But often, windows said "unknown device". So I remove the files .inf and .sys in the windows folder, i restart the computer. Then, windows said "Bilda without eeprom" but with a exclamation point in a little icon. I update the driver and it works !
Other times, this method doesn't work at all. I had tu plug and unplug it many times. At the last meeting, at the beginning it worked without problem. Later, I unplugged the DAC and projector to move it. The DAC no longer worked in the evening !
I tried with a lot of drivers like ezusb.sys, devasys.inf, ezsusbw2k.inf, ezusb2.sys...

[fesix]

I know this problem.

I only have it, when I use another USB port then normal.

Then I have to refresh the driver (ezusbw2k/bilda)

[Zatkruiers]

I have the problem, if i try to install the bilda drivers, my computer crashes, so does my other computer, any one knows what i do wrong, it is a windows XP system with service pack 3, my bilda is still without a programmed Eeprom.

[nain-nain rom]

With this driver, it should work

[Zatkruiers]

If i try to find new hardware, and select the .inf, the computer doesn't find any drivers for hardware, i am going crazy. And if i plug the usb in my computer the board is being installed as a unknown usb device, and can't update the driver to an other, is that right? Because popelscan doesn't see any output board's.

[nain-nain rom]

Install the DAC Bilda as unknown device like you said. Then plug the USB wire, plug the power wire, unplug the power wire and plug it. I have to that to recognize the DAC as Bilda USB device. But I don't use Popelscan, I use He Laserscan.

[Zatkruiers]

Thank you, now i want tot test my print, is it possible to connect mots1 motor, and how do i do that? For the properties of the mots1 : http://store.qkits.com/moreinfo.cfm/MOTS1

[Zatkruiers]

With He-laserscan ML_driver do i need for the linux-laser.org DAC? I tried them al, and could'nt find any hardware devices

[Dr.Ulli]

Please remember: He-Laserscan V does not support the BILDA, anymore!

[nain-nain rom]

Yes, It's too bad

[Zatkruiers]

Wich version did support bilda? and with witch driver?

[nain-nain rom]

All versions before the He Laserscan V support Bilda with the driver I posted here few days ago.

[Zatkruiers]

Mine steppers still don't move, but what voltage does the output from the bILDA have, when i draw a line it gives only 0.43V and -0.43V. Can anyone meassure his output? I'm getting irritated about it...

[nain-nain rom]

The DAC output voltage isn't continuous, voltage change very quickly. You should use an oscilloscope to see the signal, not a voltmeter.

[Zatkruiers]

Next problem, i bought galvo's but i can't get a good picture out of it, some times when the bilda is a time on it displays my picture but al the other times it looks like:


Anyone a idea what is going wrong?

[fesix]

The picture isn't working so please upload it here on the board.

[Zatkruiers]

Sorry, i fixed the hotlink protection.

[fesix]

Well... wat does it look like when it works?

Wich Galvos do you use? Scanspeed?

More data please!

[Zatkruiers]

The galvo's that i used are http://cgi.ebay.nl/20Kpps-laser-scannin ... 076wt_1139,
it must look like a outlined "Z". The voltage going in the bILDA is +12,47 and -12,03. The wall outled has no ground. The scanning speed i tried 2000 to 16000, in popelscan if the gain is off i get a square, and if put it higher you get like the pictures, if i use HE-laserscan it is the same.

[fesix]

What do you mean by "The wall outled has no ground"?

Of course you get a square when you put the gain down because you loose solution.

[Zatkruiers]

I get a outlined square, like the biggest it can get, but with no ground i mean, that it has no earthing (masse), but if you look at picture on top, you can see a Z, but in peaces each corner got a piece.

[fesix]

I don't know what exactly is the problem but maybe you should conect the ground from the bILDA to those of the scanners.

[Zatkruiers]

My bILDA doesn't work anymore, but if i meassure tthe output, pin 1 and 2 are now - and 14 and 15 is +, that is wrong, some one any idea what is broken on my board?

[Zatkruiers]

I solved the problem it was a ic, but the next problem and hopefully the last one, ik bought a laser http://www.dealextreme.com/p/100mw-650n ... -12v-46394 with a TTL blanking port, can i connect this to the blanking port on the bILDA? and how do i know wich wire goes where, i konw wich 2 are for green and red.
